PURPOSE AND SCOPE
As requested, K & A Engineering, Inc. has completed a limited evaluatIon of soils at the Subject site of the
construction of a single.family residence on lot 14 01 the St. LucIa Park subdivision. The purpose of this
, . - 'evaluation was to determine the suitability of the s~e for construction of the propos8d\conventlonally framed~,.,.
structures on cast..in-place concrete spread footlnas and to make recommendations for preparation of the IIi'
foundation pad.
FOUNDATION PREPARATION
The site Is located on a flat lot south of Main Street off of a new extension of Aster Street There were no signs
of significant unstable areas (tension cracks, depressions, scarps) at the time of our inspection or during
excavation,
SOils at the site consisted of 1.0 to 1.5..1eet of loose brown organIc SILTS (topsoil) over 1.5 to 2.5-189t of
brown, moderately dense, damp, moderately plastic Sll T over tan/orange..stained. very stiff to hard, very
weathered tuffaceous SILTSTONE. The brown, moderately plastic si~s are slightly to moderately expansive.
Groundwater was not encountered in the excavation.
Preparation of the foundation pads was made according to our on-site recommendations, and consisted of
stripping the organic surface soils and silts to undisturbed brown silts or slltsto!'le to a depth ranging from 2 to
3.5-fa8t
Approximately 12 to 24-ll1ches of select granular fill consistIng of 3-inch dens811raded quarry rock was placed
In 12.inch (ma)(lmum) lifts and compacted uSing a steel-wheeled vibratory roller until no further deformation
was evident during compaction at the edges of the roller. - -. , ,~':i-\'-
